Exo Active Member Jan 27, 2004 #2 As far as I know they're esentially the same. A resonator just has the 2 little cap's you need built into it.

panic mode Well-Known Member Jan 27, 2004 #5 yes and if it doesn't work, add those little capacitors...

Yes, generally if it's got three pins it's got internal capacitors, if it's only got two pins, it needs external ones.
